curve form, so polymorphic site-index curves resulted for these two conditions. Longleaf pine plantation site-index curves for these three planting-site conditions were derived from plots remeasured through ages 15 to 17 or 20 to 22 years. Modification of the curves may be necessary as more data become available. INTRODUCTIONCited by: 4. Site index curves generated from this formula are shown in Figures. 2 and 3. SUMMARY. Height growth functions have been created to predict height of dominant and codominant loblolly and slash pine growing on old- field sites in the Post Oak Belt of Texas. Each function was trans- formed into an anamorphic site index equation. The site index.

Intermediate thinnings are recom mended for jack pine stands on the better sites (site index 60 or more) managed for the production ofpoles and small saw logs.

Stn., Portland, Oreg. This paper presents height growth and site index curves and equations for even-aged, managed stands of ponderosa. The jack pine budworm, native to North America, has a range that coincides almost exactly with jack pine, its preferred host. Root borers, root feeders, shoot and stem borers, leaf feeders, needle miners, and sucking insects affect the survival and growth of seedlings. Many other insects feed on jack pine cones. Young stands of jack pine. site curve systems for western larch (Larix occidentalis), ponderosa pine (Pi- nus ponderosa), or lodgepole pine (Pi- nus contorta var. latifolia). The purposes of this paper are to compare several site curve systems for these species to data collected in western Montana, and to provide a new set of height growth and site index curves for each. -Shortleaf Pine Œ International & Doyle-Loblolly Pine Œ International, Doyle, Scribner, & Pulpwood Site index ratings for upland oaks on adapted soils are shown in Section II of the technical guide.

Red Pine in the North Central Region Compiled and Edited by: Daniel W. Gilmore and Brian J. Palik Appendix A.—Site Index Curves for Red Pine From Different Regions of red pine forests range from nearly pure stands to mixtures of jack pine, eastern white pine, aspen, paper birch, and oaks. On moister sites, red pine is found growing with. more than journals and over 2, books and book series volumes, as well as providing an extensive range of online main regions, the North, Northeast, Central, South, and Bangkok. Site index (base age 25) to 60 feet in steps of 10 Age from seed to 40 years, by intervals of 5. Methods of collecting the data and construct-ing the tables are discussed in the sections im-mediately following. The tables mere derived through a system of equations to predict number of surviving stems per acre, diameter distribu-. Carmean et al. () provided seven sets of site index curves for red pine using various index ages. Although an index age of 50 is commonly used, some of them use younger index ages. These curves are representative of height growth patterns for red pine based on total tree age, plantation age, and age measured at breast height (measured at ft or m above the .
